Parapuzosia is an extinct genus of desmoceratid ammonites from the Cenomanian to the Campanian of Africa, Europe, and North America.

[2] They are typically very large ammonites, reaching diameters of 60 cm (2.0 ft) or more, with the largest species measuring around 2 m (6.6 ft).

[3] It possesses a moderately involute shell with flat or slightly rounded sides.

Distinct primary and secondary ribbing can be observed in the inner whorls.

[4] The origin of the generic name Parapuzosia ("similar to Puzosia") comes from the smaller, related desmatoceratid Puzosia.
